Use f(x) = 2x-9 and g(x)=9-x^2 to evaluate g(f(3))

Keith_Richards [23]

Answer:

g(f(3)) = 0

Step-by-step explanation:

f(x) = 2x - 9

f(3) = 2(3) - 9

f(3) = -3

g(-3) = 9 - (-3)^2

g(-3) = 9 - 9

g(-3) = 0

Isaac and Albert spot a hot air balloon flying at a low altitude. They decide to calculate its height by standing 400 feet apart

yarga [219]

Answer:

144 feet to nearest foot.

Step-by-step explanation:

Let the distance between Albert and the point on the ground that the balloon is directly above be x feet Then for Isaac the distance is 400 - x feet

So we have 2 right angled triangles and:

tan 62 = h/x

tan 48 = h / (400- x) where h is the height of the balloon.

From the first equation x = h / tan 62 so plugging this into the second one:

tan 48 = h / ( 400 - h/tan 62)

h = 400 tan 48 - h tan 48 tan 62

h + h tan 48 tan 62 = 400 tan 48

h ( 1 + tan48 tan62) = 400 tan48

h = 400 tan 48 / (1 + tan 48 tan 62)

= 143.8 feet.

Catherine studied 1.25 hours for her science test. This was 0.5 hours less than she studied for her algebra test. Write and solv

tia_tia [17]

1.25 - 0.5 = 0.75

1.25 hours = 1 hour 15 minutes
0.5 hours = 30 minutes

1 hour 15 minutes - 30 minutes = 45 minutes

Liz is buying a home for $426,000. She is making a 22% down payment and financing the rest with a 20-year loan at 5.25% interest

olga55 [171]

Answer:

$869,776

Explanation:

1. Mortgage table

Find attached a sample of a mortgage table per 1,000 dollars borrowed.

You have to use the number in the intersection of the row for 5.25% interest and the column for 20 years.

The number is $6.74.

That means that, for every $1,000 borrowed for 20 years at 5.25% interest you will pay $6.74 every month.

2. Amount borrowed

You will make a 22% down payment:

$22\%\times \$ 426,000=\$ 93,720$

Thus the amount borrowed is $426,000 - $93,720 = $332,280

3. Monthly payment

Multiply the monthly payment per 1,000 by the amount borrowed divided by 1,000:

$\$ 6.74\times 322,280/1,000=\$ 2,239.57$

4. Total monthly payments:

Multiply the number of payments by the monthly payment.

Number of payments = 20 years × 12 payments /year = 240 payments.

$\$ 2,239.57\times 240=\$ 537,496.13$

5. Total payment for the home.

The total payment for the home will be the down payment plus the amount paid to the bank:

$322,280 + $537,496 = $869,776
